Stainless steel chemical centrifugal pump production

IHStainless steel chemical centrifugal pumpWhen the pump is filled with water, the impeller rotates to generate centrifugal force. The water in the impeller channel is thrown outwards and flows into the pump casing under the action of centrifugal force. As a result, the central pressure of the impeller decreases, which is lower than the pressure inside the inlet pipe. The water flows into the impeller from the suction tank under the pressure difference. This way, the water pump can continuously absorb water and supply water.

Stainless steel chemical centrifugal pumpDifferent forms of mechanical seals can be installed according to different usage conditions, such as internal single end balanced and unbalanced types, double end balanced and non flat balanced types, external mechanical seals, etc. The usage methods and precautions also vary depending on the selected sealing type. Below are only a few general precautions to be taken.

1. Due to the fact that mechanical seals are generally suitable for use in clean, non suspended particle media, newly installed pipeline systems and liquid storage tanks should be carefully flushed to prevent solid impurities from entering the mechanical seal end face and causing seal failure.

2. In media that are prone to crystallization, when using mechanical seals, attention should be paid to frequent flushing. Before restarting after parking, clean the crystals on the mechanical seal.

3. Disassembling mechanical seals should be done carefully, and it is not allowed to use hammers, irons, or other tools to strike, in order to avoid damaging the sealing surfaces of the dynamic and static rings.

4. If there is dirt that cannot be removed, try to remove the dirt, rinse it clean before disassembling to avoid damaging the sealing components.

5. Before installing mechanical seals, all sealing components should be checked for failure or damage, and if so, repaired or replaced.

6. The relative friction sealing surface between the moving ring and the stationary ring should be strictly inspected, and no minor scratches, bumps, or other defects are allowed. All other components, including the pump body, impeller, sealing chamber, etc., should be washed clean before assembly, especially the dynamic and static ring surfaces, which should be carefully wiped clean with a clean, soft cloth or cotton yarn, and then coated with a layer of clean grease or engine oil.

7. During assembly, attention should be paid to eliminating deviations. When tightening screws, they should be tightened evenly to avoid deviation and seal failure.

8. Correctly adjust the compression amount of the spring. After the pump is installed, when manually pulling the rotor, you should feel that the sealing spring has a certain compression amount and can rotate quickly and flexibly without feeling tight. If it feels too tight or cannot be moved, it should be loosened appropriately.

9. For mechanical seals with external flushing, the flushing fluid should be turned on before starting to fill the sealing chamber with sealing fluid. When parking, stop the pump first and then turn off the sealing flushing liquid.
